WebFluorine is the chemical element with the symbol F and atomic number 9. Its atom is the third smallest among all elements with an atomic radius of 153 pm. It has 9 electrons that surround the nucleus of its atom — 7 in its outer shell, and 2 in its inner shell. Its atomic weight is 18.998403 and its density is 0.001696 g/cm 3. WebAug 15, 2024 · Its atomic number is 9 and its atomic weight is 19, and it's a gas at room temperature. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive. It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). Chemistry of Chlorine (Z=17)
What is the difference between reactive and non-reactive metals?
WebUses. Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers. It is also used to keep satellite instruments cool and was used to cool the liquid oxygen and hydrogen that powered the Apollo space vehicles. WebIt also has the most number of nonmetals, namely five, among all periods. The elements in period 2 often have the most extreme properties in their respective groups; for example, fluorine is the most reactive halogen, neon is the most inert noble gas, and lithium is the least reactive alkali metal. cities around el paso texas
